Mawenzi was first collared in April 2017 and is with 78 kilogram currently the largest collared male in the Okonjima Nature Reserve. He was named after one of the volcanic cones of Mount Kilimanjaro. Prior his collaring, Mawenzi was regularly observed on our remotely-triggered wildlife camera traps which enabled us to thoroughly follow his change of range from the western part of the reserve to the central-eastern part and ultimately establishing a territory in the south-east of the reserve. Mawenzi is often seen with Electra and her young cub suggesting that he is the sire of her cub.
